Intel® Xeon™ Platinum 8280

The Intel Xeon Platinum 8280 is a server processor with 28 cores and 56 threads, built on the Cascade Lake architecture. It launched in Apr 2019. Clocks run from 2.7 GHz base to 4.0 GHz boost. A 38.5-MB L3 cache backs the cores (2.4 MB per core). It addresses DDR4 memory up to 1024 GB across 6 channels. The chip drops into the FCLGA3647 socket and exposes PCIe 3.0 (48 lanes). Rated TDP is 205 W. Notable platform capabilities: AVX-512, Extended Page Tables (EPT).

The Intel Xeon Platinum 8280 scores 2,196 in single-core performance and 31,287 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 8,289 for overall performance, 23,411 for productivity performance, 21,161 for creator performance, 41,846 for engineering performance and 14,410 for gaming performance. Its multi-core throughput works out to 1,117 per core, 559 per thread and 153 per watt. Its computed efficiency index is 579. Its performance index is 103, so its overall performance is 3% above the Intel Core i5-12400 (index 100). Each bar shows the score as a share of a reference ceiling, which is the larger of the 99th-percentile score across the Feex CPU database and a fixed baseline.

Scores for individual PassMark CPU Mark test categories. Higher is better. These are measured test scores, not computed from the single-core and multi-core ratings.

In the individual workload tests the Intel Xeon Platinum 8280 scores 165,721 in integer math, 102,165 in floating-point math, 710,718 in compression, 11,514 in cryptography, 1,473 in physics simulation, 54,190 in vector SIMD, 111 in the prime sieve and 74,861 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 181% above in integer math, 123% above in floating-point math, 212% above in compression, equal in cryptography, 35% above in physics simulation, 249% above in vector SIMD, 66% above in the prime sieve and 230% above in sorting. Each bar shows the score as a share of that workload's reference ceiling, the larger of the 99th-percentile score across CPUs with a recorded value and a fixed baseline.

The Intel Xeon Platinum 8280 has 28 physical cores and runs 56 logical threads. It runs 2 threads per core. It runs at a base clock of 2.70 GHz and boosts up to 4.00 GHz.

The Intel Xeon Platinum 8280 is a server processor, belongs to the Intel Xeon Platinum family, uses the Cascade Lake architecture, carries the codename Cascade Lake and is manufactured on a 14 nm process. It launched in Apr 2019.

The Intel Xeon Platinum 8280 has 1 MB of L1 cache, 28 MB of L2 cache and 38.5 MB of L3 cache. That adds up to about 67.5 MB of cache, or 2.41 MB per core.

The Intel Xeon Platinum 8280 has a 3-level cache hierarchy: L1 at 1 MB, L2 at 28 MB and L3 at 38.5 MB. L3 is the largest level and makes up about 57% of the cache listed here.

The Intel Xeon Platinum 8280 supports DDR4 memory, addresses up to 1,024 GB of memory, uses 6 memory channels, runs memory at up to 2,933 MT/s and delivers up to 140.8 GB/s of memory bandwidth. It does not support DDR5 and LPDDR memory.

The Intel Xeon Platinum 8280 does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Xeon Platinum 8280 uses the FCLGA3647 socket, supports PCI Express 3.0 and provides up to 48 PCIe lanes.

The Intel Xeon Platinum 8280 has a rated TDP of 205 W.
